Draw Chat is a free service that allows anyone to create a video chat over a whiteboard, PDF, image, or map. To use Draw Chat you just have to visit the site and click "Start New Whiteboard." Once your whiteboard launches you will have the option to enable access to your webcam and microphone. You can have people join your whiteboard video conference by sending them the link assigned to your whiteboard. Draw Chat allows you to draw or type on a shared whiteboard. Additionally, you can upload a PDF or an image to annotate on the whiteboard. A fourth option for drawing on Draw Chat is to import the URL for a Google Map and draw on that map.
Skype Interviews is a free Microsoft service that was developed for employers to use to interview potential employees. It was specifically designed with coders and programmers in mind as there is a code editor component that lets candidates display their skills in realtime. Yesterday, Microsoft added a whiteboard to Skype Interviews. The whiteboard in Skype Interviews allows you to draw on and share a virtual whiteboard while in your call. You can also type on the whiteboard. A few pre-made shapes are also available to add to your whiteboard to create a flowchart.
Realtime Board is an online whiteboard tool that I have been recommending for the last half-dozen years. At its basic level Realtime Board provides a blank canvas on which you can type, draw, and post pictures. You can connect elements on your boards through a simple linking tool. Realtime Board includes an activity tracking feature. This feature lets you see the changes that have been made to a shared Realtime Board whiteboard.
WebRoom is a free service for hosting online meetings. WebRoom doesn't require you to download any software and you don't need to register in order to use it.

You can draw on the whiteboard or upload a file to share and discuss on the whiteboard. A text chat space is provided in each WebRoom meeting. It is possible to share your screen with other meeting participants. However, to share your screen you will need to install the WebRoom Chrome extension.
